With all the recent announcements from Google I/O, Microsoft’s Bing replacement of Live Search, and Yahoo’s shuttering of GeoCities and Yahoo 360, it feels like search is changing in front of our eyes and that somehow SEO (define) must be changing, too. Yet SEO has always been a moving target.

随着Google I/O的推出，随着微软新搜索引擎Bing的推出，随着雅虎GeoCities的亮相，各大搜索引擎都在大变脸，因此，SEO不可避免地面临调整。当然，SEO一直是一个变化的因素。

Even if Google has broadened its abilities to crawl JavaScript and Flash, AJAX (define) remains problematic with its unchanging URL structure. Even if Microsoft’s Bing makes inroads on local, shopping, travel, and health vertical search patterns, the market share it could gain won’t likely come from Google. Even if Wolfram Alpha has accelerated the closure of Yahoo 360 and blogging has eroded GeoCities, search remains a primary compass for navigation on the Web.

即使谷歌拓展其JavaScript和Flash的能力，AJAX对于不变的URL结构来说仍存在问题。即使微软的Bing向本地、购物、旅行以及保健等垂直搜索市场进军，其获得的市场份额肯定不会是来自谷歌的。即使Wolfram测试版本的推出加速了雅虎360的关闭，博客正在向GeoCities渗透，搜索仍是网络上一种主要的活动。

In its fundamental nature, search itself hasn’t changed. There have been no sweeping algorithmic updates with this storm of developments, even though algorithms are always bubbling and percolating behind the scenes. Nearly half the online population in the United States still uses search engines every day — many of whom are simply seeking out information relevant to their queries.

从本质上讲，搜索自身不会发变改变。在这场开发风暴中，没有出现运算规则的升级，尽管运算一直在幕后变化。在美国，有近一半的人每天仍在使用搜索引擎，他们许多人只查询相关的信息。

Relevancy remains the primary objective of any search engine if it is to serve users well. Toward this end, the fundamental elements of SEO haven’t changed.

相关性仍是许多搜索引擎的最主要目标，如果它想为用户提供更好的服务。朝着这个目标，SEO的基础仍未发生变化。

SEO hasn’t really changed. It’s still based on building a search engine friendly site structure around great content that naturally inspires inbound links, trust, and user interaction.

SEO仍未发生根本变化。它仍基于开发搜索友好型网站结构，围绕出色内容吸引内部链接，提高可信度，增强用户交互性。
